How can we increase the cybersecurity in our IT infrastructure in a time where cyber-attacks are becoming both more common and advanced?

The cyber threat landscape is constantly changing, making it an expert’s game to keep an eye on and overview of all assets in the network. Some of the challenges when securing the IT infrastructure of an organisation might be:

  • Lack of full visibility across the network in both physical, virtual and cloud environments makes it difficult to fully determine the risks and hence manage them properly. 'Sectorial' understanding of IT infrastructure brings failure to discover the links between the assets, potentially comprising the security or resulting in incompliancy with guidelines.

  • Lack of full overview with detailed reports, summed up data and intuitive dashboards make it difficult to communicate risks and put cybersecurity on the agenda in the organisation.

  • Updates and configurations on assets and devices are being overlooked or manifest like a potential vulnerability, bringing 'noise' to the threat analysis.
